Abstract: SiO2 -Al2 O3 -RO (where R is a bivalent metal) glass which has a high specific elasticity larger than 36 .times. 10 6 Nm/kg or a high Young's Modulus larger than 110 GPa and has a high transition temperature (high heat-resistance) higher than 700 .degree.C. A glass substrate which has an excellent surface smoothness (surface roughness Ra < 9.ANG.) and a high strength can be provided by using this glass. Since the glass has the excellent heat-resistance, the glass substrate is not deformed during the heat treatment which is necessary for the improvement of the characteristics of a magnetic film. Since the glass substrate has the excellent surface smoothness, the reduction of the floating height of a magnetic head (i.e. the increase of the recording density) can be achieved. Since the glass substrate has a large specific elasticity and a large strength, the thickness of a magnetic disc can be reduced and, further, the breakage of the magnetic disc can be avoided.

Abstract: A universal synchronizer for use in a variety of telecommunications systems based on direct digital phase synthesis (DDPS) include digital and analog PLLs. The synchronizer may be used for wireless, optical, or wireline transmission systems and for a wide ranges of data rates. Digital phase detectors are used in the digital PLLs for comparing the phase of the local clock f L with the phase of a respective digital reference clock, and provides a respective phase error signal. A digital phase synthesis unit receives the phase error signal and a target phase error and produces a first and a second set of control signals for driving an error driver. The error driver generates the control voltage for adjusting the frequency of a VCXO that is used for all PLLs, to lock the respective PLL. The first set of control signal generates the control voltage for the digital PLLs, and the second set of control signals generates the control voltage for the analog PLLs and for the acquisition mode of operation of all PLLs. The frequency and the width of the members of the first and second set of control signals are adjusted with a density width code, which is calculated for a target value and for the specific configuration of the synchronizer.

Granted: 2007-01-02
Abstract: A hinged fastener is provided for splicing transverse ends of conveyor belts together with the belt fastener having teeth that are bent from one of the fastener plates for piercing and sinking into the belt to increase the holding power of the fastener. In the preferred form, the fastener is attached to the belt end with two rivets with the teeth being adjacent the rivets to provide a small, low cost, high performance fastener. The teeth are formed by bending them down from the outer edge of the plate and about a bend line parallel to the inner edge of the plate so that the teeth face the belt end to keep the teeth from being pulled through the belt material. The location of the teeth adjacent the rivets maximizes the depth of penetration of the teeth into the belt for improved fastener holding power and minimizes the likelihood that the teeth will be bent upward and lose holding power when the belt is highly tensioned.

Title: Axial ejection in a multipole mass spectrometer
Inventor: HAGER JAMES W
IPC: H01J49/42
Filed: 1997-06-02
Granted: 2007-01-16
Abstract: A method of operating a mass spectrometer having an elongated multipole rod set, in which a two-dimensional RF field radially contains trapped ions in a mass to charge range of interest, and in which the ions are contained axially by a barrier field on an end lens and to which a low voltage DC is applied. Trapped ions are axially mass selectively ejected by taking advantage of the mixing of the degrees of freedom induced by the fringing fields and other anti-harmonicities in the vicinity of the end lens. Thus, ions can be mass selectively ejected at the exit end at the same time as ions are being admitted into the entrance end of the rod set, thereby taking better advantage of the ion flux from a continuous ion source. The axial mass selective ejection is performed by applying an auxiliary AC voltage to the end lens, and by scanning either the auxiliary AC voltage or the RF voltage on the rod set. Trapped ions can be concentrated near the exit lens by applying an axial field in the direction of the lens, or can be depleted by applying the axial field in the opposite direction. The axial field can be oscillated to dissociate trapped ions.

Abstract: An electrochemical converter is disposed within a pressure vessel that collects hot exhaust gases generated by the converter for delivery to a cogeneration bottoming device, such as a gas turbine. The bottoming device extracts energy from the waste heat generated by the converter, such as a fuel cell for the generation of electricity, yielding an improved efficiency energy system. Bottoming devices can include, for example, a gas turbine system or a heating, ventilation or cooling (HVAC) system. The pressure vessel can include a heat exchanger, such as a cooling jacket, for cooling the pressure vessel and/or preheating an input reactant to the electrochemical converter prior to introduction of the reactant to the converter. In one embodiment, a compressor of a gas turbine system assembly draws an input reactant through the pressure vessel heat exchanger and delivers the reactant under pressure to a fuel cell enclosed therein. Pressurized and heated fuel cell exhaust gases are collected by the pressure vessel and delivered to the turbine system expander. The fuel cell and the pressure vessel function as the combustor of the gas turbine assembly. The expander can perform mechanical work, or can be coupled to a generator to provide electrical energy in addition to that provided by the fuel cell. Also disclosed is a feedthrough for transferring a fluid, such as exhaust gases or an input reactant, from outside the pressure vessel to within the pressure vessel.

Abstract: The invention relates to a downhole seal (10) of the balloon type, formed to sealingly bear, in use, by its outer circumferential surface on, for example, the inner shell surface of a production riser (12). To prevent that the pressure inside the inflated seal, because of temperature variations, either gets so high that the seal (10) bursts, or so low that the seal (10) loosens and loses or reduces its effect, the seal (10) has a thereto connected pressure compensator (16), which is arranged to adjust the internal pressure of the inflated seal (10) in relation to the pressure of the surroundings on the underside/downstream of the seal, which will thus make a true reference pressure for the internal pressure of the seal (10). By increasing pressure inside the inflated seal (10) the ambient pressure permits a leakage of the liquid/gaseous inflating medium of the seal to maintain a largely constant internal pressure in the seal (10), whereas by a falling pressure inside the seal (10), the ambient pressure causes it to rise by supplying additional inflating medium from a reservoir (26), to maintain the pressure desired for the seal (10).

Abstract: Piping support of gas turbine steam cooled combustor is improved such that, even when the piping support is damaged by combustion vibration, piping is prevented from dropping so as to avoid the occurrence of fractions thereof from entering into the turbine portion. An outer fitting member (11) is fixed to the wall surface of a tail tube (102) by welding (82, 83). A ring (12) is pinched inside the outer fitting member (11) to be fixed by welding (80). The ring (12), having an inner diameter slightly larger than the outer diameter of the steam piping (101), is fitted in around the steam piping (101) to be fixed by welding (81) at three places. The steam piping (101) is fixed to the ring (12), the ring (12) is fixed to the outer fitting member (11), and the outer fitting member (11) is fixed to the tail tube (102), such that the steam piping (101) is supported to the tail tube (102). Thus, even when the welding (82, 83) is detached by combustion vibration, the outer fitting member (11) remains fixed to the steam piping (101).
